First, the correct use of LED lights

1. Frequently turning on and off the light will reduce the life of the light. If you only leave for 5 minutes and come back, there is no need to turn off the lights, but if you leave for a period of time, you must turn off the lights at will, which will save energy and money.

2. The use of modulators, especially when watching TV, can reduce the brightness of electric lamps, which can save electricity and reduce the glare of brightness displayed on the fluorescent screen of the TV.

3. Regular cleaning, wipe off the dust on the bulb with a dry cloth, so that the bulb will not be covered by dust and the brightness is not enough, and the brightness must be turned up, wasting electricity.

4. Don't think that fewer lights save more electricity. Putting electric lights in the space where there is a need can be used to illuminate at any time, but it will save a lot of unnecessary electricity costs. For example, if a small light is needed in the storage room, it is not necessary to always light up a small space and put the whole relatively small space. The lights in the large space were turned on.

Second, LED energy-saving lamps to buy

1. The LED brightness (MCD) is different and the price is different. The LEDs used for LED lamps should meet the laser class I standard.

2. Antistatic ability. LEDs with strong anti-static ability have a long life and are therefore expensive. Usually LEDs with anti-static greater than 700V can be used for LED lighting.

3. LEDs with the same wavelength have the same color. If the same color is required, the price will be high. It is difficult for manufacturers without LED spectrophotometers to produce products with pure color.

4. Leakage current LED is a unidirectional conductive luminous body. If there is a reverse current, it is called leakage current. LEDs with large leakage current have short life and low price.

5. LEDs with different lighting angles have different lighting angles. special

Lighting angle, the price is higher. Such as the full diffusion angle, the price is higher.

6. The lifespan is different. The key to quality is life, which is determined by light decay. Small light decay, long life; long life, high price.

7. The light-emitting body of chip LED is a chip, and the price of different chips varies greatly. Chips in Japan and the United States are more expensive. Generally, the prices of chips in Taiwan and China are lower than those in Japan and the United States.

8. Chip size The size of the chip is represented by the length of the side. The quality of the large chip LED is better than that of the small chip. The price is proportional to the wafer size.
